Washington, June 24 : A new study by researchers from the University of Chicago, US, has shown that the way mothers interact with their babies in the first year of life is strongly linked to how children behave later on.

According to Benjamin Lahey and his colleagues from the university, both a mother's parenting style and an infant's temperament reliably predict challenging behaviour in later childhood.

For the study, researchers looked at whether an infant's temperament and his mother's parenting skills during the first year of life might predict behavioral problems, in just over 1,800 children aged 4-13 years.

Measures of infant temperament included activity levels, how fearful, predictable and fussy the babies were, as well as whether they had a generally happy disposition.

The researchers examined how much mothers stimulated their baby intellectually, how responsive they were to the child's demands, and the use of spanking or physical restraint.

Child conduct problems in later childhood included cheating, telling lies, trouble getting on with teachers, being disobedient at home and/or at school, bullying and showing no remorse after misbehaving.

The study indicated that both maternal ratings of their infants' temperament and parenting styles during the first year are surprisingly good predictors of maternal ratings of child conduct problems through age 13 years.

Researchers also found that less fussy, more predictable infants, as well as those who were more intellectually stimulated by their mothers in their first year of life, were at low risk of later childhood conduct problems.

Early spanking also predicted challenging behaviour in Non-Hispanic European American families, but not in Hispanic families.

According to researchers, these findings support the hypothesis that "interventions focusing on parenting during the first year of life would be beneficial in preventing future child conduct problems...

"Greater emphasis should be placed on increasing maternal cognitive stimulation of infants in such early intervention programs, taking child temperament into consideration," they added.

The study has been published online in Springer's Journal of Abnormal Child Psychology.
